Driven by the "dual carbon" goal

the new power system dominated by new energy has raised urgent demands for short-term and high-frequency energy storage technologies. This paper conducts a systematic analysis of the technical and economic characteristics of supercapacitor energy storage

establishes an evaluation model for the full life cycle cost and benefits

identifies the main obstacles affecting its development

and provides a systematic promotion path from four aspects: value accounting system

market trading mechanism

business model innovation

and policy guarantee. Through research

it is found that optimizing and integrating the system

entering the auxiliary service market

and considering the hybrid energy storage scheme of supercapacitors can significantly improve the economic situation of the project. It is expected that by 2030

the levelized energy storage cost of such projects will be more than one-third lower than the current level. The research results can provide a theoretical basis and decision-making support for the industrialization development of supercapacitor energy storage in the context of "dual carbon".
